Troubleshooting Checklists
If an error condition exists with the printer, review this checklist:
Is there an error message on the LCD? If yes, see LCD Error Messages on page 119
.
Are noncontinuous labels being treated as continuous labels? If yes, see
and Ribbon Sensor Sensitivity on page 88 .
Is the
CHECK RIBBON light on when ribbon is loaded properly, or are noncontinuous
labels being treated as continuous labels? If yes, see Calibrate Media and Ribbon Sensor
Are you experiencing problems with print quality? If yes, see
Print Quality Problems on page 122 .
Are you experiencing communications problems? If yes, see Communications Problems on page 126 .
If the labels are not printing or advancing correctly, review this checklist:
Are you using the correct type of labels? Review the types of label in Types of Media on page 25
.
Are you using a label that is narrower than the maximum print width? See
.
Does the printhead need to be adjusted? See
Adjust Printhead Balance and Pressure on page 68
for more information.
Do the sensors need to be calibrated? See
Calibrate Media and Ribbon Sensor Sensitivity on page 88
for more information.
If none of the above suggestions correct the problem, review this checklist:
Perform one or more of the self-tests given in
Printer Diagnostics on page 130
. Use the results to help identify the problem.

Caution • An improperly connected printhead data or power cable can cause this error message. The printhead may be hot enough to cause severe burns. Allow the printhead to cool.
The printhead is under temperature.
Continue printing while the printhead reaches the correct operating temperature. If the error remains, the environment may be too cold for proper printing. Relocate the printer to a warmer area.

Disconnect and reconnect the data cable to the printhead.
3.
Ensure that the cable connector is fully inserted into the printhead connector.
4.
Turn on ( I ) the printer.
Free up some of the printer’s memory by adjusting the label format or printer parameters. One way to free up memory is to adjust the print width to the actual width of the label instead of leaving the print width set to the

Printer Diagnostics
Printer Diagnostics
Self tests and other diagnostics provide specific information about the condition of the printer.
The self tests produce sample printouts and provide specific information that helps determine the operating conditions for the printer. The most commonly used are the Power-On and the
CANCEL self tests.
Important • Use full-width media when performing self tests. If your media is not wide enough, the test labels may print on the platen roller. To prevent this from happening, check the print width using
, and ensure that the width is correct for the media that you are using.
Each self test is enabled by pressing a specific control panel key or combination of keys while turning on ( I ) the printer power. Keep the key(s) pressed until the first indicator light turns off.
The selected self test automatically starts at the end of the Power-On Self Test.
Note •
• When performing these self tests, do not send data to the printer from the host.
• If your media is shorter than the label to be printed, the test label continues on the next label.
• When canceling a self test prior to its actual completion, always reset the printer by turning it off ( O ) and then on ( l ).
Power-On Self Test
A Power-On Self Test (POST) is performed each time the printer is turned on ( l ). During this test, the control panel lights (LEDs) turn on and off to ensure proper operation. At the end of this self test, only the POWER LED remains lit. When the Power-On Self Test is complete, the media is advanced to the proper position.
To initiate the Power-On Self Test, complete these steps:
The POWER LED illuminates. The other control panel LEDs and the LCD monitor the progress and indicate the results of the individual tests. All messages during the POST display in English; however, if the test fails, the resulting messages cycle through the international languages as well.

FEED Self Test
Different types of media may require different darkness settings. This section contains a simple but effective method for determining the ideal darkness for printing bar codes that are within specifications.
During the FEED self test, labels are printed at different darkness settings at two different print speeds. The relative darkness and the print speed are printed on each label. The bar codes on these labels may be ANSI-graded to check print quality.
The darkness value starts at three settings lower than the printer’s current darkness value
(relative darkness of –3) and increase until the darkness is three settings higher than the current darkness value (relative darkness of +3).
The speed at which labels are printed during this print quality test depend on the dot density of the printhead.
• 300 dpi printers: 7 labels are printed at the 2 ips and 8 ips print speeds.
• 203 dpi printers: 7 labels are printed at the 2 ips and 12 ips print speeds.
To perform a FEED self test, complete these steps:
1.
Print a configuration label to show the printer’s current settings.
2.
Turn off ( O ) the printer.
3.
Press and hold FEED while turning on ( I ) the printer. Hold FEED until the first control panel light turns off.
The printer prints a series of labels (

higher and lower than the darkness value shown on the configuration label.

The “in-spec” bar code can only be confirmed by a verifier, but it should exhibit some visible characteristics.
• The normal bar code will have complete, even bars and clear, distinct spaces.
• The rotated bar code will have complete, even bars and clear, distinct spaces. Although it may not look as good as a slightly dark bar code, the bar code will be “in-spec.”
• In both normal and rotated styles, small alphanumeric characters look complete.
Slightly light labels are, in some cases, preferred to slightly dark ones for “in-spec” bar codes.
• Both normal and rotated bar codes will be in spec, but small alphanumeric characters may not be complete.
Labels that are too light are obvious.
• Both normal and rotated bar codes have incomplete bars and spaces.
• Small alphanumeric characters are unreadable.

Add or subtract the relative darkness value from the darkness value specified on the configuration label. The resulting numeric value (0 to 30) is the best darkness value for that specific label/ribbon combination and print speed.

Communications Diagnostics Test
The communication diagnostics test is a troubleshooting tool for checking the interconnection between the printer and the host computer.
When the printer is in diagnostics mode, it prints all data received from the host computer as straight ASCII characters with the hex values below the ASCII text. The printer prints all
characters received, including control codes such as CR (carriage return). Figure 38 shows a
typical test label from this test.
Note • The test label prints upside-down.

To use communications diagnostics mode, complete these steps:
1.
Set the print width equal to or less than the label width being used for the test. See
for more information.
2.
Set the printer to DIAGNOSTICS. For instructions, see
Set Communications Mode on page 91
.
The printer enters diagnostics mode and prints any data received from the host computer on a test label.
3.
Check the test label for error codes. For any errors, check that your communication parameters are correct.
Errors show on the test label as follows:
• FE indicates a framing error.
• OE indicates an overrun error.
• PE indicates a parity error.
• NE indicates noise.

• If the media sensor incorrectly identifies preprinted areas on a label as gaps (web).

Calibrate Media and Ribbon Sensor
Ribbon Sensor Profile ( Figure 39 ) The bars (

Media Sensor Profile ( Figure 40
